Line 1:

'''Kenilworth''' is a village located in [[Cook County, Illinois]], approximately 17 miles north of downtown [[Chicago]]. It is the newest of the eight suburban "[[North Shore]]" communities bordering [[Lake Michigan]], and is the only one developed as a planned community. Department store mogul Joseph [[Sears]] purchased 223.6 acres in one of the last undeveloped areas near Chicago's lakeshore for $150,300 in [[1889]]. Seven years later the population had reached 300 residents, fulfilling the legal requirement for incorporation. As of the [[2000]] census, the village had a total population of 2,494.

[[Image:Pigpen.png|thumbnail|right|The pigpen cipher uses graphical symbols assigned according to a key similar to the above diagram.]]

The '''pigpen cipher''' (sometimes called the '''masonic cipher''' or '''Freemason's cipher''') is a simple [[substitution cipher]] exchanging letters for symbols based on a grid. The use of symbols is no impediment to [[cryptanalysis]] however, and cryptanalysis is identical to that of other simple substitution schemes. The example key shows one way the letters can be assigned to the grid.

Kenilworth has a reputation as the wealthiest and most exclusive community in [[Chicagoland]]. In April of 2005, American Demographics magazine named Kenilworth's [[zip code]] (60043) the 11th most affluent in the U.S.

The scheme was developed and used by the [[Freemasons]] starting in the early [[1700]]s for record-keeping and correspondence.

==Example Geography ==

Kenilworth is located at 42°5'17" North, 87°42'57" West (42.088128, -87.716009){{GR|1}}.

Using the example key, the message "<tt>X marks the spot</tt>" is rendered in ciphertext as:

<div align="center">[[Image:A-pigpen-message.png|320px|An example pigpen message]]</div>

not true as i am a freemason. and none of the symbols i see or read in my lodge are anywhere close to those

According to the [[United States Census Bureau]], the village has a total area of 1.6 [[square kilometer|km&sup2;]] (0.6 [[square mile|mi&sup2;]]). 1.6 km&sup2; (0.6 mi&sup2;) of it is land and none of it is covered by water.

As of the [[census]]{{GR|2}} of [[2000]], there are 2,494 people, 792 households, and 697 families residing in the village. The [[population density]] is 1,604.9/km&sup2; (4,190.8/mi&sup2;). There are 815 housing units at an average density of 524.5/km&sup2; (1,369.5/mi&sup2;). The racial makeup of the village is 97.27% [[White (U.S. Census)|White]], 0.16% [[African American (U.S. Census)|African American]], 0.04% [[Native American (U.S. Census)|Native American]], 2.25% [[Asian (U.S. Census)|Asian]], 0.00% [[Pacific Islander (U.S. Census)|Pacific Islander]], 0.00% from [[Race (U.S. Census)|other races]], and 0.28% from two or more races. 1.36% of the population are [[Hispanic (U.S. Census)|Hispanic]] or [[Latino (U.S. Census)|Latino]] of any race.

There are 792 households out of which 49.9% have children under the age of 18 living with them, 81.7% are [[Marriage|married couples]] living together, 5.6% have a female householder with no husband present, and 11.9% are non-families. 10.2% of all households are made up of individuals and 6.4% have someone living alone who is 65 years of age or older. The average household size is 3.15 and the average family size is 3.39.

Out of the total people living in poverty, none are under the age of 18 and 1.7% are 65 or older.
